摘要

The absorption spectra of CuI nanocrystals with an average radii of 5.3 and 6.2 nm in photochromic glass matrix have been studied in the temperature range 38-300 K. It has been established that the copper iodide nanocrystals, like copper chloride and copper bromide nanocrystals of the same sizes, predominantly crystallize in a nonequilibrium form different from the stable low-temperature cubic modification. The structure of metastable modifications of copper halide nanocrystals in photochromic glasses has been discussed.
